US 8,408,054 B2 · Method and device for carrying out an adaptation and a diagnosis of emission-relevant control devices in a vehicle

Abstract

A method and system for adapting the operation of emission-relevant control devices of a vehicle in a predetermined driving mode having a shorter expected duration that a duration of a preferred test cycle may include several steps. A first step may include determining whether the vehicle has reached the predetermined driving mode. A second step may include diagnosing at least one parameter associated with operation of at least one of the emission-relevant control devices. A third step may include comparing the at least one parameter with a setpoint range or a setpoint value. A fourth step may include carrying out at least a first section of an adaptation for the operation of the at least one emission-relevant control devices. The first section of the adaptation may include optimizing at least one of a plurality of operating points of the at least one emission-relevant control devices.

Dependent claims

A method for adapting operation of emission-relevant control devices of a vehicle in a predetermined driving mode, the method comprising the steps of:

Determining whether the vehicle has reached the predetermined driving mode having a shorter expected duration than a duration of a preferred test cycle;
If the vehicle has reached the predetermined driving mode, diagnosing at least one parameter associated with operation of at least one of the emission-relevant control devices;
comparing the at least one parameter to a setpoint range or a setpoint value;
and
if the at least one parameter deviates from the setpoint range or the setpoint value, carrying out at least a first section of an adaptation for the at least one emission-relevant control device, the first section of an adaptation including optimizing at least one of a plurality of operating points of the at least one of the emission-relevant control devices.

2 more elements

A device for controlling the operation of emission-relevant control devices of a vehicle in a predetermined driving mode, comprising:

a driving mode determination device operable to determine whether the vehicle has reached the predetermined driving mode having a shorter expected duration than a duration of a preferred test cycle;
a diagnosis device diagnosing at least one of the emission-relevant control devices, if the driving mode determination device establishes that the vehicle has reached the predetermined driving mode, by determining at least one parameter of an operating point of at least one emission-relevant control device, and
an adaptation device executing at least a first section of an adaptation for the at least one emission-relevant control device if the diagnosis device determines that the at least one parameter is outside of a setpoint range, the first section of the adaptation optimizing the at least one parameter of the operation point of the at least one emission-relevant control device.
